出于安全原因，文件 mail.php 具有 env 变量形式的键值，您必须在名为 .env 的单独文件中设置这些值（我在下面提供了一个示例），当然，您可以使用您拥有帐户的任何免费邮件提供商，例如 gmail、hotmail、yandex 等。
首先这是配置中的mail.php文件
'driver' => env('MAIL_DRIVER', $_ENV['MAIL_DRIVER']),
/*
|--------------------------------------------------------------------------
| SMTP Host Address
|--------------------------------------------------------------------------
|
| Here you may provide the host address of the SMTP server used by your
| applications. A default option is provided that is compatible with
| the Mailgun mail service which will provide reliable deliveries.
|
*/
'host' => env('MAIL_HOST', $_ENV['MAIL_HOST']),
/*
|--------------------------------------------------------------------------
| SMTP Host Port
|--------------------------------------------------------------------------
|
| This is the SMTP port used by your application to deliver e-mails to
| users of the application. Like the host we have set this value to
| stay compatible with the Mailgun e-mail application by default.
|
*/
'port' => env('MAIL_PORT',$_ENV['MAIL_PORT']),
/*
|--------------------------------------------------------------------------
| Global "From" Address
|--------------------------------------------------------------------------
|
| You may wish for all e-mails sent by your application to be sent from
| the same address. Here, you may specify a name and address that is
| used globally for all e-mails that are sent by your application.
|
*/
'from' => ['address' => 'beauty@beauty.com', 'name' => 'My App'],
/*
|--------------------------------------------------------------------------
| E-Mail Encryption Protocol
|--------------------------------------------------------------------------
|
| Here you may specify the encryption protocol that should be used when
| the application send e-mail messages. A sensible default using the
| transport layer security protocol should provide great security.
|
*/
'encryption' => env('MAIL_ENCRYPTION', 'ssl'),
/*
|--------------------------------------------------------------------------
| SMTP Server Username
|--------------------------------------------------------------------------
|
| If your SMTP server requires a username for authentication, you should
| set it here. This will get used to authenticate with your server on
| connection. You may also set the "password" value below this one.
|
*/
'username' => env('MAIL_USERNAME', $_ENV['MAIL_USERNAME']),
/*
|--------------------------------------------------------------------------
| SMTP Server Password
|--------------------------------------------------------------------------
|
| Here you may set the password required by your SMTP server to send out
| messages from your application. This will be given to the server on
| connection so that the application will be able to send messages.
|
*/
'password' => env('MAIL_PASSWORD', $_ENV['MAIL_PASSWORD']),
/*
|--------------------------------------------------------------------------
| Sendmail System Path
|--------------------------------------------------------------------------
|
| When using the "sendmail" driver to send e-mails, we will need to know
| the path to where Sendmail lives on this server. A default path has
| been provided here, which will work well on most of your systems.
|
*/
'sendmail' => '/usr/sbin/sendmail -bs',
];
这里是 .env 文件
MAIL_DRIVER=smtp
MAIL_HOST='smtp.gmail.com'
MAIL_PORT='465'
MAIL_USERNAME='beauty@beauty.com'
MAIL_PASSWORD='yourpassword'
MAIL_ENCRYPTION=null
然后在您的控制器中，您需要编写邮件代码，如下所示。如您所见，我附上了一张图片，其中名称取自从表单发送的变量，但您可以用硬编码字符串替换它们以进行测试。
您最不需要的是实际发送到收件人电子邮件的视图，在这种情况下，我们称之为“邮件程序”，看起来像这样：
